ROOF-PAINT.

SPECIFICATION forming part of Letters Patent No. 394,318, dated December 11, 1888.

Application filed July 13, 1886- Serial No. 207,910. (No specimens.)

To (LZZ Hill 077$ it may concern:

Be it known that I, .TUNIUs I \VASHBUEN, a citizen of the United States, residing in Jersey ()ity, in the county of Hudson and State of New Jersey, have invented a new and useful (omposition of Matterto be ['sed in Painting- Roots, of which the following is a specification.

My composition consists of the following ingredients, which are combined in the proportions stated, as follows: Coal-tar, three hundred (300) pounds; ground soapstone, twenty (20) pounds; peroxide of iron, twenty-five pounds.

The coal-tar, if applied to a painted roof, should first be heated, so that it may penetrate the old paint. The remaining in gredients are then added, the whole being thoroughly mixed by stirring. The composition is then applied with brushes, and spread upon the surface to which it is applied to any desired thickness. Common sandis then sprinkled upon the composition in order to prevent running, and it soon hardens and forms a dense but elastic coveringywhicb is absolutely water-proof, and which will not crack or peel off.

I am aware that a patent hasbeen granted for a roof-paint consisting of peroxide of iron, llydraulic cement, soapstone, gypsum, and coal-tar. Such a compound I do not claim.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The herein-described composition of matter to be used for painting root's, consisting of coal-tar, ground soapstone, and peroxide of iron, in the proportions specified.
